AbstractIn recent years, cardiopulmonary resuscitation (CPR) has been discussed as a cause of petechial hemorrhage in eyelids and conjunctivae, which could be of substantial significance to forensic expertises in cases of suspected strangulation. In the reported series or case observations, the combination of CPR and petechiae seemed to be sufficient to explain such a causal connection. Nearly all presented cases were victims for which the mechanisms resulting in death were themselves well-known causes explaining the development of such petechiae; and said mechanisms can frequently be observed in victims that did not receive CPR. An earlier, also retrospective, analysis of a series of forensic autopsies did not confirm CPR as a significant cause of conjunctival petechiae. Now we present the result of a prospective examination of 196 resuscitations of adult patients with separate assessment of petechiae being present even prior to resuscitation. Petechiae were present in 12 cases - but in eight of them prior to resuscitation already. Three other persons with petechiae found only after CPR were in the group of successfully resuscitated persons and exhibited petechiae hours after CPR during therapy in intensive care units - during a phase of ongoing cardiac insufficiency, which obviously caused them. The only case with petechiae observed neither immediately prior to nor after unsuccessful resuscitation, but during a follow-up examination one day later, needs to be discussed. It is not interpreted as reliable evidence for the causality of CPR though. Our interpretation of reports in literature as well as our experiences confirm the absence of actual proof of petechiae being generated by CPR and in the presence of generally significant doubts of this relation.Copyright 2009 Elsevier Ltd and Faculty of Forensic and Legal Medicine.
